IntelliJ IDEA 2017.2 Help

Phusion Passenger Special Notes

This feature is supported in the Ultimate edition only.

The following is only valid when Ruby Plugin is installed and enabled!

Phusion Passenger (including version 5 with the code name Raptor) can be selected as a Rails server in a Rails run/debug configuration.


  • The corresponding gem should be installed. If the gem is missing, IntelliJ IDEA suggests to install it.

Notes and limitations

  • Raptor support is available for macOS and Linux systems.
  • IntelliJ IDEA creates an initializer file config/initializers/rubymine-passenger-debug.rb.
  • Phusion Passenger initializer is used only for Phusion Passenger debugger; execution of Rails applications is not affected.
  • Use Phusion Passenger with only those settings that are specified in the console.
  • The Phusion Passenger prespawn script should load the dynamic content generated by Rails, but not a static page.
